STEAM-BOILER CLEANER.

SEECIFICATION forming part of Letters Patent No. 325,476, datedSeptember 1, 18,85.

Application tiled J une 27, 1885.

To @ZZ whom it may concern:

Be itknown that I, HENRY B. BAKER, a citizen of the United States,residing at Hulls, in the county of Athens and State of Ohio, haveinvented certain new and useful Improvements in Steanroiler Cleaners,and I do declare the following to be a full, clear, and exact descrip- 1tion of the invention, such as will enable others skilled in the art towhich it appertains to make and use the same, reference being had to theaccompanying drawing, and to letters or figures of reference markedthereon, which form a part of this specication.

The figure of the drawing is a representa1 tion of vertical sectionalView.

Myinvention has relation to automatic or seliactin g water-agitators forsteam-boilers and steamboiler cleaners combined; and it consists in theconstruction of parts, as will behereinafter fully described,andparticularly pointed out in the claims.

Referring by letter to. the accompanying drawing, A desi gnatesasteam-boiler,in which the dotted lines X X designate the water-line inboiler. B designates a horizontal pipe extending the entire length ot'the boiler, near the bottom of the same,and projecting th rough bothheads of the boiler at B and B.

C C desiguatejam-mits on the pipe B,whicl1 arc screwed firmly againstpacking to make the joints tight where the pipe B goes th rough theboiler-heads and to hold the pipe B lirrnl y to its place. D designatesa short curved pipe or, joints which enters the top of the boiler at F.A vertical glass sight-tube, Gr, connects the front projecting end ofthe pipe B with the short curved pipe D,suitab1e joints, I-I H H H,being employed for this pnrpose.

The end lof the pipe B that projects through the rear end or head oftheboiler is provided with a stop cock or valve, J. Intermediate of theboiler-heads the horizontal pipe B is provided with a number of shortdownwardlycurved tubes or small pipes, K,whieh connect with the lowerside of said pipe B and extend quite near to the bottom of the boiler.The lower ends of said pipes K are reduced onehalf in size.

In the rear boiler-head and quite near to the bottom of the boiler Iprovide a blow-off pipe, L, which is provided with a stop-cock orblow-off valve, M.

The two stopcocks N and N are only for a convenience to stop or shut offthe steam (No model.)

above and the water below the glass tube G in case of accident in anyway to said tube.

The use of the glass siglittube G is to see when the pipe B is clear ofwater and the device is at work.

Theoperation of the invent-ion is as follows: When it is desired to putit in operation, the stop-cock or blow-oft` valve .I is opened and thewater is permitted to escape from the horizontal pipe B, and the pipe Bwill fill with steam from the top of the boiler at F, and then thestop-cock or blow-off valve .I is closed. Then from the pipe B the steamwill passinto the pipes K to their discharge'points, where it willremain unt-il the cock M has been opened, when thcsuetion on the pipesK, caused by the iow ot water through the boiler to the discharge-pipeL,will cause the steam to discharge from said pipes K in the bottom ofthe boiler, which will aid materially in generating more steam, and atthe same time move any sediment or dirt np to the blow-0H pipe L, wherethe dirt or sediment can be blown out through the blowbtf pipe L,thereby keeping the boiler clean all the time and aid materially ingenerating steam; hence a saving of fuel.

The number and the size ot' the small curved tubes or pipes K may bevaried without departing from the character of the invention.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent of the United States, is-

1. The combination, with a steam-boiler having the blow-off pipe withstop cock or valve in one head near the bottom, of the pipe B withcurved tubes K and stop cock or Valve J, the short pipe D, and thesight-tube G, substanti ally as specified.

2. rIhe combination, with a steam -boiler having the blow-off with stopcock or valve, of the horizontal pipe B, extending entirely through theboiler and projecting at each end thereoand provided with small curvedpipes K, the short curved pipe D, and the vertical tube connecting thepipes B and D, substantial] y as specified.

In testimony whereof I affix my signature in presence of two witnesses.
